It's really strange that it all of a sudden tries to lookup this google_compute_engine module out of python2.7 folder.

Upstream boto problem? I could try to pin my boto dependency to ==2.45.0 and see if it works.

Thanks for any help.

Possibly related? Maybe this is happening because TravisCi is behind the scenes running on google cloud?

boto/boto#3741

[nackjicholson]

Okay, I see this export BOTO_CONFIG=/dev/null in the moto .travis.yml.

I guess I have to do the same if I'm running a build on travis. If this isn't in your README or docs somewhere yet, it might be helpful to shout it out. This is a very wierd bug. Have you considered just dropping support for boto? 😆

[spulec]

Have you considered just dropping support for boto? <-- ha!

I think you are right that this is mostly a boto issue. I don't have a great place in the docs or README to add this, but hopefully people will find this issue going forward.
